BT TECH AV Mount BT8309/B

The BT8309 is designed to install small to medium screens into recessed walls. The pop-out mechanism allows for a flush to the wall installation while still allowing access to the rear of the screen for easy installation and service access. Tool-less micro-adjustment is included on each corner to allow screens to perfectly align to the recess and additional screens in a videowall installation. BT8309 also allows screens to be mounted in landscape or portrait orientation and is compatible with B-Tech's professional pole and collar system for pole-mounted installs.
